FOOD-TREATING MACHINE.

Application filed. September 16, 1912.

To all wiz-0m may concern:

Be it known that l, CHARLES H. J. Dino, a citizen of the United States, residing in the borough of the Bronx, city ot New York, county of New York, and. State of New York, have invented a certain. new and useful Improvement in Foodflreating Machines, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

My invention relates to food treating devices and particularly to devices adapted for mashing or reducing foods, such as fruits or herbaceous plants, meats, etc., to a pulp or soft mass and straining the juice therefrom.

One object ot' my invention is to provide a device ot' this class which may be readily and easily converted from a pressing into a rubbing device, and vice versa.

Another object of my invention is to provide simple and effective means for thoroughly mixing and churning the substance being treated.

Another object is to provide simple and reliable means for preventing the holes of the toraminous plate or strainer from becoming clogged.

@ther objects et my invention are simplicity, durability and economy in construction, and reliability and vfacility in operation.

Still other objects and advantages of my invention will appear from the following description.

My invention consistsof various novel 'features ot construction and combinations of parts, as will hereinafter more fully appear.

I shall now describe the embodiment of my invention illustrated in the accompan fing drawings and shall thereafter point out my invention in claims.

Figure l is a side elevation ol a complete device embodying my invention. Fig. 2 is a vertical section of the same taken on the line 22 of Fig. l, looking toward the right. Fig. 3 is a horizontal section of the same taken on the line 3 3 of Fig. l, looking down. Fig. 4l is a view corresponding to Fig. l, with the handle removed and with the side toward the observer partially broken away to show t-he interior, and showing one screen in its lower or rubbing position. Fig. t1 is a detail in side elevation ot the other screen removed.

Serial No. 720,655.

The illustrated embodiment of my invention consists of a casing or recelfitacle, two removable toraminous plates or screens, a treat-ing member or paddle, and means ttor operating the treating member. The casing is supported on suitable legs and is substantially cylindrical or drum shaped, and is formed of a lower substantially semi-circular half or portion l having an open bottom, and an upper half or portion 2 surmounted by a suitable hopper 3, shown as formed integral therewith. The two halves are se curedtogether byl bolts. A central transverse shaft d is removably mounted in suitable bearings in the casing and is provided on one end with a crank 5 for manual operation. To act upon the material in the casing, a treating member or paddle 6 is provided, which is secured to the shaft 4t and extends radially therefrom in a plane substantially parallel to that of the handle 5. At its outer end this paddle may be provided with some yieldable treating material 7, as bristles.

To mash, eomminute or strain the contents ot the receptacle,two oraminous plates or screens 8 are provided, which are substantially arcuate, shown as practically so, though multi-angular plates composed ot a succession of plane portions would serve substantiallythe same purpose. Hereinafter I shall refer to these plates and their support4H ing grooves as arcuate. According to the manner in which it is desired to treat the material, means are provided in the casing of the' receptacle for receiving and holding these screens in two positions, the screens being adapted to be removably held in either position. To hold the screens in the path of the paddle in position to be enga-ged by the faces of the paddle in its rotation, the side walls ot' the lower portion l oit the casing are provided with two arcuate channels or grooves extending from the center to the periphery on substantially opposite sides ot the sh att 4:, as shown particularly in F ig. 4, arranged so that the screens will be disposed in these grooves 9 with their concave sides upward. The screens may be inserted into these grooves S) from the inner ends ot the grooves after the shaft t is removed, and it is apparent that in this position ot the screens the paddle 6 will approach the screens tacewise and a positive pressure device is formed, by means of which the contents of the receptacle may be mashed into a pulp, and the reduced portions forced through the screens or plates 8 and the skins,

seeds and other residue, if there be any, will be separated and left behind upon the screens. The faces of the paddle 6 are preferably made convex so as to conform to and fit into the concave sides of the screens, whereby pressure is exertedV equally upon all parts of the screens. The paddle 6 may also be provided with perforat-ions l0, as shown in Figs. l, 3 and 4, so that the contents of the receptacle will be forced through these apertures and a churning action result by which the contents will be thoroughly mixed. lThe paddle is also preferably made t0 have substantially an air-tight fit with the sides of the casing, so that, as the paddle is withdrawn from the screens S,V a suction holes in the screens from becoming clogged.

to a pulp must pass through the holes in` the screen. The device may, therefore, be continuously operated and the paddle reciprocated without interrupt-ion during the feeding of material into the receptacle. This is important in the case of hot vegetables,

such as potatoes to be mashed, asL it enables` the vegetables to be rapidly operated upon, with little or no loss of'heat..

hen the device isto operate wit-h a rubbing action, the screens 8 are removed from the position shown in Figs. l, 2 and 3, and are disposed end to end substantially parallel to the arcuate path of the outer edge of the treating member or paddle 6. To hold the screens in this position, means are provided in the side walls of the bottom of the lower portion l of the casing comprising an arcuate slot ll in one side wall and an arcuate channel or groove l2 in the opposite side wall, the slot and the groove being each concentric with or parallel to the arc of movement of the outer edge of the paddle 6 and being arranged so that when the screens 8 are placed therein, they complete the periphery of the receptacle and a continuous inner face or surface is thereby formed whereby the paddle may describe an uninterrupted circular movement. In this case, the bristles 7 are desirable, and as these bristles pass across the plates or screens 8, they impart a lrneading or rubbing action to 55 the contents, thereby rubbing the contents will be produced, which will prevent thel these slots until their inner edges enter the grooves l2. The curve of the arcuate screens is such that they form arcs concentric with the periphery of the receptacle and they may therefore be readily inserted in either of their two positions. It will be manifest that when disposed in their pressing position, the screens create a coarse mash; while in their rubbing position they cause the substances to be rubbed very line before they are forced through the screens. Thus in the case of tomatoes, the fruit may be by the first operation forced through the plates 8 in the form of a coarse sauce or stew, or by the second operation may be rubbed through the screens in the consistency of a line strained pure or jelly.

It is obvious that various modifications may be made in the construction sho-wn and above particularly described within the principle and scope of my invention.
